KieranB: /* Basics */

=Introduction=
This page contains a brief introduction to the Quantum GIS software (QGIS). QGIS is a Free Open Source Software which for more information please see the QGIS website [http://www.qgis.org/ www.qgis.org/]. The basics of QGIS, particularly with respect to TUFLOW modelling are described below, each of these has a separate page. If you have any suggestions to be included in these pages, please add them to the discussion page. [[Talk:QGIS_Tips | Please add QGIS Suggestions Here!]].

QGIS uses ArcGIS file formats for vector data, with data stored in shapefiles (.shp). QGIS, however, is able to read in MapInfo files directly. In the shapefiles, points, lines and regions are stored in separate files. 
If you are using QGIS as your model development or result viewing environment we strongly recommend installing the [[TUFLOW_QGIS_Plugin| TUFLOW QGIS Plugin]]. It includes numerous tools to increase workflow efficiency. It also includes powerful result viewing functionality via its [[TUFLOW_Viewer | TUFLOW Viewer]].

=Basics=
In this section are some basic GIS functions that are regularly used in creating TUFLOW models in QGIS.
